Yep! This is one reason why I argue we should do lowish power density fusion, in space, using the vacuum of space. There’s a nice set of existence proofs, and the gentle magnetic fields do a much better job of confining energyhttps://twitter.com/michael_nielsen/status/1223291031338115072 …

it could be *vastly* better than chemical rockets for interplanetary. the rocket equation flips around -> increasing exhaust velocity yields exponentially greater payload. trips to mars go from 2 yrs 1% payload to like 50% payload 90 days. might flip the bit on feasibility.
Thanks. Twitter will use this to make your timeline better. UndoUndo
